In this article we will write a go language program to check if a given number is finite or not. The program uses IsInf() and IsNaN() library functions in order to check whether numbers are finite or not. Syntax func IsInf(f float64, sign int) bool IsInf() function is present in the math package. This function takes two arguments one is the floating point number that we wish to check and the other is the sign. The sign is an integer which can be greater than, lesser than, or equal to zero. If the sign is greater than zero then ... Read More
An array in go language is defined as the data structure that is used to store elements in contiguous memory locations. Arrays allow us to search and store elements at constant time. arrays use index to store elements which starts from 0 and goes to n – 1, where n is the length of the array. Method 1: Using An External User-Defined Function The following method, illustrates how we can remove a particular integer element from the array of integers using an external function. Algorithm Step 1 − Import the fmt package. Step 2 − Defining a function named ... Read More
An array in go language is defined as the data structure that is used to store elements in contiguous memory locations. Arrays allow us to search and store elements at constant times. arrays use the index to store elements that start from 0 and goes on to n – 1, where n is the length of the array. Algorithm Step 1 − First, we need to import fmt package. Step 2 − Now, start the main() function. Inside the main() initialize an array of strings. Step 3 − In order to add values to this array we have to ... Read More
What is a 2D array? A two-dimensional array is a collection of data that are arranged in rows and columns. In go we can use the for loops to iterate and print elements of the 2d arrays. Here is an example of the same below − 0 1 2 4 5 6 8 9 10 Method 1: Using For Loops In this method, we will use for loops in golang to iterate over the arrays and catch each element then we will print that element unless the whole array is iterated upon. Algorithm ... Read More
A matrix is a collection of numbers arranged in rows and columns, a two-dimensional array, each of the values of this matrix is known as an element. Here we will use three methods to find the sum of column elements and compare each method for the same using go programming. Here is an example of a matrix and the sum value of it’s columns − The given matrix is − 0 1 2 4 5 6 8 9 7 Sum of elements in column 1 is 12 Sum of elements in column 2 ... Read More
A matrix is a collection of numbers arranged in rows and columns, a two-dimensional array. Here we will use three methods to find the sum of elements and compare each method for the same using Go Programming language. Algorithm Step 1 − Import the fmt package. Step 2 − Now we need to start the main() function. Step 3 − Then we are creating a matrix naming matrix. Step 4 − Print the matrix on the screen using fmt.Println() function. Step 5 − Initialize a new variable called sum of type int to hold the resultant sum. Step ... Read More
What are Objects in Golang? Objects are defined on the structs and store Key-value pairs of data together in go programming. There are numerous methods for producing an object. A struct is a user-defined type that groups together a collection of fields (also known as properties or data members) and methods. A struct can be defined using the type keyword, followed by the struct name and a struct literal that defines the fields of the struct. Method 1: Using a user-defined function Algorithm Step 1 − First, we need to import the fmt package. Step 2 − Then we ... Read More
What is a Matrix? A matrix is a collection of numbers that are arranged in rows and columns, which is a two-dimensional array. Here we will use three examples to find the sum of elements and compare each element of the matrix for the same using the Golang program. Algorithm Step 1 − Import the fmt package. Step 2 − Now we need to start the main() function. Step 3 − Then we are creating a matrix naming matrixA. Step 4 − Print the matrix on the screen using fmt.Println() function. Step 5 − Initialize a new variable called ... Read More
The price range selector allows us to select two values representing the range. Sometimes, we require to create a range slider to allow users to select a range. For example, we can allow users to select a minimum and maximum price using the price range selector. We can also show the products by filtering based on the selected minimum and maximum prices. In this tutorial, we will learn to create a price range selector using various libraries in ReactJS. Using the material UI to create a range selector The material UI provides various components we can import into the ... Read More
Nowadays, applications use a one-time password or magic link for authentication, but we can’t ignore the authentication using the username and password. Whenever we allow users to register with a username and password, we should ensure that the password users have entered is strong. So, it can be unbreakable by hackers. In this tutorial, we will learn to verify the security level of the password in ReactJS. Create a Custom Validation Algorithm We can create a custom validation algorithm to check if the password is strong or weak. We can create regular expressions for lowercase, uppercase, and numeric ... Read More
